Financial Data Extraction from Investing.com with Python

Financial Data Extraction from Investing.com with Python

investpy is a Python package to retrieve data from Investing.com, which provides data retrieval from up to: 39952 stocks, 82221 funds, 11403 ETFs, 2029 currency crosses, 7797 indices, 688 bonds, 66 commodities, 250 certificates, and 2812 cryptocurrencies.

investpy allows the user to download both recent and historical data from all the financial products indexed at Investing.com. It includes data from all over the world, from countries such as United States, France, India, Spain, Russia, or Germany, amongst many others.

investpy seeks to be one of the most complete Python packages when it comes to financial data extraction to stop relying on public/private APIs since investpy is FREE and has NO LIMITATIONS. These are some of the features that currently lead investpy to be one of the most consistent packages when it comes to financial data retrieval.

:hammer_and_wrench: Installation

To get this package working you will need to install it via pip (with a Python 3.6 version or higher) on the terminal by typing:

$ pip install investpy

Additionally, if you want to use the latest investpy version instead of the stable one, you can install it from source with the following command:

$ pip install git+https://github.com/alvarobartt/investpy.git@master

The master branch ensures the user that the most updated version will always be working and fully operative so as not to wait until the the stable release comes out (which eventually may take some time depending on the number of issues to solve).

:computer: Usage

Even though some investpy usage examples are presented on the docs, some basic functionality will be sorted out with sample Python code blocks. Additionally, more usage examples can be found under examples/ directory, which contains a collection of Jupyter Notebooks on how to use investpy and handle its data.

:chart_with_upwards_trend: Recent/Historical Data Retrieval

investpy allows the user to download both recent and historical data from any financial product indexed (stocks, funds, ETFs, currency crosses, certificates, bonds, commodities, indices, and cryptos). In the example presented below, the historical data from the past years of a stock is retrieved.

import investpy

df = investpy.get_stock_historical_data(stock='AAPL',
                                        country='United States',
                                        from_date='01/01/2010',
                                        to_date='01/01/2020')
print(df.head())

             Open   High    Low  Close     Volume Currency
Date

To get to know all the available recent and historical data extraction functions provided by investpy, and also, parameter tuning, please read the docs.

:mag: Search Data

Investing.com search engine is completely integrated with investpy, which means that any available financial product (quote) can be easily found. The search function allows the user to tune the parameters to adjust the search results to their needs, where both product types and countries from where the products are, can be specified. All the search functionality can be easily used, for example, as presented in the following piece of code:

import investpy

search_results = investpy.search_quotes(text='apple',
                                        products=['stocks'],
                                        countries=['united states'],
                                        n_results=10)

Retrieved search results will be a list of investpy.utils.search_obj.SearchObj class instances. To get to know which are the available functions and attributes of the returned search results, please read the related documentation at Search Engine Documentation. So on, those search results let the user retrieve both recent and historical data from that concrete product, its information, etc., as presented in the piece of code below:

 for search_result in search_results[:1]:
   print(search_result)
   search_result.retrieve_historical_data(from_date='01/01/2019', to_date='01/01/2020')
   print(search_result.data.head())

{"id_": 6408, "name": "Apple Inc", "symbol": "AAPL", "country": "united states", "tag": "apple-computer-inc", "pair_type": "stocks", "exchange": "NASDAQ"}

:money_with_wings: Crypto Currencies Data Retrieval

Cryptocurrencies support has recently been included, to let the user retrieve data and information from any available crypto at Investing.com. Please note that some cryptocurrencies do not have available data indexed at Investing.com so that it can not be retrieved using investpy either, even though they are just a few, consider it.

As already presented previously, historical data retrieval using investpy is really easy. The piece of code presented below shows how to retrieve the past years of historical data from Bitcoin (BTC).

import investpy

data = investpy.get_crypto_historical_data(crypto='bitcoin',
                                           from_date='01/01/2014',
                                           to_date='01/01/2019')

print(data.head())

             Open    High    Low   Close  Volume Currency

2014-01-03  856.9   888.2  839.4   884.3    9709      USD
2014-01-04  884.3   932.2  848.3   924.7   14239      USD
2014-01-05  924.7  1029.9  911.4  1014.7   21374      USD

:sparkles: Contribute

As this is an open-source project it is open to contributions, bug reports, bug fixes, documentation improvements, enhancements, and ideas. There is an open tab of issues where anyone can open new issues if needed or navigate through them to solve them or contribute to its solving. Remember that issues are not threads to describe multiple problems, this does not mean that issues can not be discussed, but so to keep structured project management, the same issue should not describe different problems, just the main one and some nested/related errors that may be found.

:question: Discussions (Q&A, AMA)

GitHub recently released a new feature named GitHub Discussions (still in beta). GitHub Discussions is a collaborative communication forum for the community around an open source project.

Check the investpy GitHub Discussions page at Discussions, and feel free to ask me (ar any developer) anything, share updates, have open-ended conversations, and follow along on decisions affecting the community's way of working.

:pushpin: Note. Usually I don't answer emails asking me questions about investpy, as we currently have the GitHub Discussions tab, and I encourage you to use it. GitHub Discussions is the easiest way to contact me about investpy, so that I don't answer the same stuff more than once via email, as anyone can see the opened/answered discussions.

:card_index_dividers: Related projects

Since investpy is intended to retrieve data from different financial products as indexed in Investing.com, the development of some support modules which implement an additional functionality based on investpy data, is presented. Note that anyone can contribute to this section by creating any package, module, or utility that uses investpy. So on, the ones already created are going to be presented, since they are intended to be used combined with investpy:

• pyrtfolio: is a Python package to generate stock portfolios.
• trendet: is a Python package for trend detection on stock time-series data.

If you developed an interesting/useful project based on investpy data, please open an issue to let me know to include it in this section.
